Lists can be nested to arbitrary depth. Lists are mutable. Lists are dynamic. Each of these features is examined in more detail below. Remove ads Lists Are Ordered WebMathematicians commonly consider ordered pairs ; for instance, most analytical geometry is done with Cartesian coordinates ( x , y ), an ordered pair, double, or 2-tuple. An essential ingredient here is that a tuple has a fixed and known number of elements. For example a 2-dimensional geometric point might have a tuple with x and y .

I am new to python, and I am trying to generate ordered pairs, and then evaluate the Domain and Range of the set relation. My issue with my current code is that it sets up the list just fine, but rather than giving me the actual ordered pair, it gives me (what I am assuming is) the address of the ordered pair. WebSep 25, 2024 · Generate all possible pairs (i, j) and check if a particular ordered pair (i, j) is such that, (arr i, arr j) satisfies the given equation of the line y = mx + c, and i ≠ j. If the point is valid (a point is valid if the above condition is satisfied), increment the counter which stores the total number of valid points. Implementation: C++ Java
